Odor-spreading speaker device

Abstract

An odor-spreading speaker device includes a voice coil assembly and a fragrant sheet for spreading a certain odor. The voice coil assembly at least includes a vibration diaphragm, a separation ring, a magnet member, a yoke, a vibration coil, and a circuit board. The vibration diaphragm, the separation ring, and the magnet member are sequentially stacked with one another. The yoke at least surrounds the magnet member. The vibration coil assembly is disposed between the magnet member and the yoke, and the vibration coil assembly surrounds the magnet member. The circuit board is electrically connected to the vibration coil assembly. The fragrant sheet is fixed to the voice coil assembly directly or indirectly. Accordingly, when the voice coil assembly is operated to make sounds, the sound vibration drives airflows to pass through the fragrant sheet, so that the odor-spreading effect can be enhanced.

What is claimed is: 
     
         1 . An odor-spreading speaker device, comprising:
 a voice coil assembly, at least comprising a vibration diaphragm, a separation ring, a magnet member, a yoke, a vibration coil, and a circuit board, wherein the vibration diaphragm, the separation ring, and the magnet member are sequentially stacked with one another, the yoke at least surrounds the magnet member, the vibration coil is disposed between the magnet member and the yoke, and the vibration coil surrounds the magnet member, and the circuit board is electrically connected to the vibration coil; and   a fragrant sheet spreading a certain odor, wherein the fragrant sheet is directly or indirectly fixed to the voice coil assembly.   
     
     
         2 . The odor-spreading speaker device according to  claim 1 , wherein the yoke is a U-shaped yoke, the yoke receives the vibration diaphragm, the separation ring, and the magnet member, and a periphery and a bottom of the magnet member are surrounded by the yoke. 
     
     
         3 . The odor-spreading speaker device according to  claim 1 , further comprising:
 a front housing, at least having a main audio output opening, wherein the main audio output opening is defined through an inner side of the front housing and an outer side of the front housing; and   a rear housing combined with the front housing to form a protecting space, wherein the rear housing has a rear opening, the yoke is engaged in the rear opening, and the vibration diaphragm is located in the protecting space, and the fragrant sheet is fixed to the front housing or the rear housing.   
     
     
         4 . The odor-spreading speaker device according to  claim 3 , wherein the fragrant sheet is disposed on an inner lateral surface of the front housing and the fragrant sheet covers the main audio output opening. 
     
     
         5 . The odor-spreading speaker device according to  claim 3 , further comprising a rear audio output opening, defined through the separation ring, the magnet member, and the yoke, wherein the fragrant sheet is disposed on a protruding portion of the yoke and the fragrant sheet covers the rear audio output opening. 
     
     
         6 . The odor-spreading speaker device according to  claim 3 , wherein the front housing further comprises a plurality of auxiliary audio output openings, the auxiliary audio output openings surround the main audio output opening and are defined through the inner side of the front housing and the outer side of the front housing, the fragrant sheet at least covers one of the auxiliary audio output openings. 
     
     
         7 . The odor-spreading speaker device according to  claim 3 , wherein the rear housing further comprises at least one auxiliary opening, and the fragrant sheet covers the at least one auxiliary opening. 
     
     
         8 . The odor-spreading speaker device according to  claim 3 , wherein the fragrant sheet is integrally formed with the front housing or with the rear housing as a whole. 
     
     
         9 . The odor-spreading speaker device according to  claim 1 , wherein the fragrant sheet is combined with the vibration diaphragm. 
     
     
         10 . The odor-spreading speaker device according to  claim 1 , wherein the fragrant sheet is disposed in the voice coil assembly and stacked with the vibration diaphragm, the separation member, and the magnet member.
